Micro or press filter type fuel cell, has assembly comprising hydrophobic and hydrophilic layers and arranged on part of outer surface of cathode, where hydrophilic layer is in contact with one of zones of surface to form water storing zone

摘要

Cell has a stack of an anode (16), an electrolytic membrane (17) and a cathode (18), and an assembly comprising an hydrophobic layer (26) and an hydrophilic layer (23). The assembly is arranged on a part of an outer surface (20) of the cathode, and the hydrophilic layer is in contact with one of zones of the surface to form a water storing zone. The hydrophobic layer is made of a material chosen among fluoropolymer, amorphous silicon oxycarbide, and carbon nanotubes and the hydrophilic layer is made of polymer, porous graphite and cured ceramic.
